Ive had my Eurgle V1 for over 12 months now. I took a while to get around it, but now its easy.

The only problem Ive found is the early ones have some bad soldering on the switches. Mine were ready to break off..
the V1 modules were made my Fly Sky not FrSky so it has no freq hopping...Im upgrading the modue when its in stock..

Well I suspect while quite a few units have shipped, very few people are actually using them every day. Extremely powerful, flexible, open and hackable hardware, a pure delight for many of us. I love the premise of the 9x radio, and enjoy playing with the capabilities of er9x and eepe.

But for many others, it is overly complicated, cryptic, and problematic. Mr Kim says to RTFM, but of course there really is no FM, though that CopterX manual seems the most english-like manual, which is good. RTFM is fine and good, but frankly the stock firmware is clunky and awkward. I'd argue that the radios are really only useful with a third-party firmware, which enables my 9x to do things that Spektrum owners can only dream about frankly. But therein lies the rub of course. To get third-party firmware installed you have to solder wires onto the circuit board. And buy an AVR adapter, and be comfortable enough with the AVR toolset to be able to push firmware to it. Also the Turnigy decision to permanently wire their removable module into the radio was really boneheaded. The 9x really could be positioned as a transmitter unit compatible with any 2.4 GHz system out there via standard modules (DSM2, FrSky, Futaba, etc).

I have an old Ergule 9channel ( I think a V10 only started using it about 8 month ago, not all the time but every now and then WHEN FLYING the switch error comes on, now that sucks. I can not see any bad solder joint anywhere on the switches.
